Have replaced the ECU ( had to use old prom) still will not start, but every once in a while fuel will intermittently spray from injector. have heard that distributor signals the fuel injection off of the position of the cam. Will install new distributor next.Have replaced the ECU ( had to use old prom) still will not start, but every once in a while fuel will intermittently spray from injector. have heard that distributor signals the fuel injection off of the position of the cam.

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's
